At a distance; standoffish (5)
I believe the answer is:
aloof
This clue is a double definition.
'at a distance' is the first definition.
(I've seen this in another clue)
'standoffish' is the second definition.
(I've seen this before)
(Other definitions for aloof that I've seen before include "Snooty" , "Cool, distant" , "Displaying supercilious reserve" , "Showing detached attitude" , "Unapproachable, distant" .)
